Public key infrastructure (PKI)
The system that manages digital certificates, those proofs of identity behind the little padlock in your browser.
A PKI creates and manages digital certificates, the equivalent of an identity card for a website or a service. It is what allows your browser to check that you are on the real site and that the connection is encrypted. Its reliability rests on trusted authorities that issue these certificates. It is a technical cog of everyday digital life.
